A short parable seems to be in order here.
There once was a large penguin rookery located on an island that was
designated as K-2.2.18. The penguin population that lived there was large
and plentiful due to the fact that it provided suitable protection and
sustenance. Due to this the population had grown large and was starting
to look for new territory to occupy. Lo and behold they discovered
a substantially larger island known as K-2.4.0 which had a wealth of
untapped resources that would allow the colony to expand in the future.
Unfortunately, the distance between K-2.2.18 and K-2.4.0 was large and
full of many unknown dangers (not the least of which were large killer
whales looking for tasty penguins to snack on).
Despite this, many of the penguin population decided that the risk and
effort necessary to reach K-2.4.0 was acceptable because of the
opportunities it provided. This divided the penguins into a number of
groups:
o Group #1 was composed of some of the elder penguins, who had made
successful ocean crossings in the past. They traveled together in a flock
so
as to mitigate their danger. They arrived successfully with only minor
injuries.
o Group #2 was formed from mature and adolescent penguins. When they
ventured forth they either swam in groups for protection or as individuals
who counted on their own strengths (speed and cunning) to insure a
successful journey. Despite this they still encountered dangerous schools
of jellyfish that inflicted damage upon some of them. These penguins
required some time to recuperate after completing their journey
Group #3 was made up of fledging penguins, who having seen others make the
journey, decided they could do so as well. They launched from shore with
a plan that consisted of nothing more than a dream of Island K-2.4.0 for
they were unexperienced in such endeavors. Many of them became lost
during the journey or were eaten by killer whales hunting for the
inexperienced. Of the remaining penguins, the majority turned back to
K-2.2.18. A few of the original group did make it K-2.4.0 and spent much
time recuperating from the exhausting swim and the mental trauma from having
seen their friends eaten.
Group #4 was all the other penguins left on K-2.2.18. These penguins waited
a number of months till the ocean calmed down and the killer whales migrated
to warmer waters. A this point the majority of them departed from K-2.2.18
for K-2.4.0 with friendly schools of dolphins to guide them (designated
Pod-RedHat, Pod-SuSe, Pod-Sistina, etc...). They arrived without incident
on K-2.4.0. Those left on K-2.2.18 maintained the rookery and lived happy
ever after.
The moral of the story -- If you are a Group #3 penguin don't expect
much sympathy from your wiser or more cautious
brethren when you get eaten.
